Pre-Peak switch — The Pre-Peak switch alters the TP signal output to correct for long
cable runs. See
for suggested switch settings based on the transmitted video
format and transmission distance.

RS-232 Insert connector —
For bidirectional RS-232 data that is routed from a common
source to the TP output regardless of the selected input, connect a serial device to this
3.5 mm, 5-pole captive screw connector.
Figure 7
shows how to wire the connector.
NOTE: For the RS-232 insert to be available on the TP output, it must be enabled
via an SIS command or the Windows-based control program. See the
NOTE: When the RS-232 insert is enabled, any content on the audio/RS-232 wire
pair for the TP input tied to the output is disabled.

Mono Audio (local audio) output —
Connect an audio device, such as an audio
amplifier or powered speakers to this 3.5 mm, 5-pole captive screw connector. This
connector outputs the selected unamplified, mono line level audio. See
figure 8
to
properly wire the output connector. Use the supplied tie-wrap to strap the audio cable to
the extended tail of the connector.

Captive screw connector wiring for audio output
CAUTION: Connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.
CAUTION: The length of the exposed (stripped) portion of the copper wires is
important. The ideal length is 3/16” (5 mm). Longer bare wires
can short together. Shorter bare wires are not as secure in the direct
insertion connectors and could be pulled out.
The volume level for the local output can be set under serial port control. See the
By default, the audio ties follow the video ties. Audio breakaway switching, which can
be performed under serial port control, allows you to select from any one of the audio
input sources and route it separately from its corresponding video source. See the
